The Digital Key Green Poly Pro is the workhorse green for keying: a uniform, saturated field that holds its color under big soft sources so post can pull a clean matte on the first pass. It rigs fast on a frame or ties off as a backdrop when the insert shot suddenly becomes a VFX shot. Sizes run from the compact 4'x4' through the full 20'x20', each one sewn in the USA by LA Rag House. A solid rag to have in the truck.
